the 5 ish dwarves on the right are all stuck. I've tried to knock them loose with a wind bomb but its not working because I'm like 3 upgrades away from fully upgrading everything. every once in a while one or two other dwarves will start veeeerrrryyy slowly moving backwards. in the picture the one just to the right of the stuck cluster is going backwards. Sorry the reply took so long. thanks for your help! :)
this is only the feeling I have in my soul. idk if it has any merit at all BUT, I think it might be an issue with the maw suction upgrade. the problem only started after the update, and about half of the dwarves running through the stuck cluster slow down to a crawl then start moving backwards. I think for some dwarves that location specifically messes up their speed and slows them down. then they cannot interact with the wall properly and turn around like they are supposed to. I think the maw suction is mapped to that location for my dumb dwarves and sucking them in for whatever reason. sorry if this is the dumbest thing in the universe haha.
I am not sure which 5 runners do you mean? The ones next to the mountain, looking to the left and carrying big piles of gems? Or do you mean that 1 runner that is somehow stuck in the mountain right at the edge of the screen? In either case it's very weird that they would be blocked by anything or moving slowly. It would be great help if you could record a video and maybe post it in discord, or at least explain it in more detail (how exactly it happened? what exactly are they doing and which dwarves exactly?). Thank you for reporting this
